_refine.ls_weighting_details

Name:
'_refine.ls_weighting_details'

Definition:

   A description of special aspects of the weighting scheme used
   in least-squares refinement. Used to describe the weighting
   when the value of _refine.ls_weighting_scheme is specified
   as 'calc'.

Example:

;                                 Sigdel model of Konnert-Hendrickson:
                                  Sigdel =
                                  Afsig +  Bfsig*(sin(theta)/lambda-1/6)
                                  Afsig = 22.0, Bfsig = 150.0
                                    at the beginning of refinement.
                                  Afsig = 16.0, Bfsig =  60.0
                                    at the end of refinement.
